I ran a diesel at the track once. Three times back to back I won two he won one. The one I lost I had bad wheelspin off the line. He was a 4x4 2500 with big off road tires but was still running 13.6 (this was obviously long before the Whipple). This was at LACR at 2700 feet and probably 90 degrees.

I hated the loss because I had to drive through all that nasty black smoke...gahhh...that sucked.
